Public bug reported:

most of fn+something don't do anything
i'm using ubuntu 10.10 64bit,
when i press some fn + function keyboard nothing happens (xev don't detect them)
more in depth, the fn not working are:

key ---- simbol on key ---- sudo showkey
fn + f5 (brightness up)      keycode 470 press
fn + f6 (brightness down) keycode 471 press
fn + f7 (lcd/VGA)              keycode 472 press
fn + f9 (magnifier minus)  keycode 474 press
fn + f10 (magnifier plus)   keycode 475 press
fn + f12 (disk->>zzz)        keycode 476 press

the only working are fn + f2, fn + f3, fn + f4

and there are also two keys called "assist" and "vaio" whitch don't work, but 
the behaviour is different
neither xev neither showkey says anything but,
after pressing "assist" dmesg says:
Unknown event: 0x100 0xa6
Unknown event: 0x100 0x26
after pressing "vaio"
Unknown event: 0x100 0xa5
Unknown event: 0x100 0x25

(PS to get the touchpad work i had to add this line to the grub, i dont know if 
it affects something
GRUB_CMDLINE_LINUX="i8042.nopnp")

PSS i attached dmesg, lspci -vv and uname -a
